How to Connect a Mac Notebook to a Projector

By Joanne Mendes

Connecting your Mac notebook to a projector allows you display images, presentations and videos saved on the computer. This can save money and time by letting you share the files at work or at home without first having to burn them to a DVD. This method also allows you to connect your Mac laptop computer to other types of display units, like external computer monitors and television sets that have computer-in ports.

Things You'll Need

  • DVI, VGA, composite, or S-video connector (depending on type of connector port on projector)
  • Mini-DVI to DVI adapter, Mini-DVI to VGA adapter or Mini-DVI to Video adapter (depending on type of connector on projector)

Mac Operating Systems X-8 and Newer

Step 1

Connect the projector's video-out connector to the Mini-DVI adaptor. Plug the connector into the projector's "Video-in" port. Plug the Mini-DVI end of the adaptor into the Mac's "Video-out" port that is located on the left-hand side of the notebook.

Step 2

Click the Mac's "Apple" icon located at the top left-hand corner of the desktop to open the main menu.

Step 3

Click "Control Panel" and select either "Monitors" or "Monitors & Sound," depending on your operating system version.

Step 4

Open the "Monitor drop-down menu" and check "Simulscan." Whatever image or video that you play on your Mac notebook will also be sent to your projector.

Mac Operating Systems X-7 and Older

Step 1

Connect the projector's video-out connector to the Mini- DVI adaptor. Plug the connector into the projector's "Video-in" port. Plug the Mini-DVI end of the adaptor into the Mac's "Video-out" port that is located on the left-hand side of the notebook.

Step 2

Click the "Finder" icon on the Mac's desktop menu and type in "System Folder." Open the folder and select the "Control Panel" folder.

Step 3

Click "Display" and check "Video Mirroring."

Step 4

Restart your notebook. After the notebook reboots, the image or video that you play on your Mac notebook will also be sent to your projector.

Tips & Warnings

  • Mac notebooks that use an NVIDIA graphics card will not work with a projector that uses an S-video connector. Notebooks that have NVIDIA graphics cards are mainly newer models that began being released in early 2009.
